Synthesis and Antiproliferative Activity of Novel Hydrazono Thiazolidene and Thiazole Derivatives Bearing Rhodanine Moiety

Some new fluoro-heterocyclic compounds containing thiazole and pyridine moities have been synthesized and studied for their antiproliferative activity. Thiazole derivatives have been synthesized by the reaction of alpha-halo carbonyl compounds with thiosemicarbazones. Some pyridine derivatives have been synthesized by the reaction of chalcone with cyanothioacetamide and/or malononitrile. Spectroscopic methods have been used for elucidating molecular structures of the products. Cytotoxic activity of several derivatives has been tested against human breast cancer (MCF-7), human colon cancer (HCT-116) and human liver cancer (Hep-G2) by the SRB method. Most of compounds exhibit mild effect on the tested cell lines. One of thiazolidin-4-one derivatives has been characterized by moderate to strong effect on MCF-7 cell line.
